The 2012 5700-C has an unladen weight of 35,060 kg and, at a gross vehicle weight of 37,000 kg, only around 1,940 kg of payload. Such a small margin between unladen and gross weight is typical of heavy special-purpose bodies whose own construction already accounts for most of the permitted weight, as with low-loaders for compact, very heavy loads. Only a small margin then remains for payload.

At this weight class, the brake system works on compressed air rather than an overrun mechanism, as EU rules require above 10 tonnes of gross vehicle weight. Towing such a trailer behind a suitable towing vehicle requires a category CE licence, and both vehicles must be compatible in their braking systems.

On a vehicle of this age, it is worth looking closely at the axles, suspension and brake system, since wear shows up there first. The frame should be free of through-corrosion, especially at welds and axle mountings. Tyres age through standing time regardless of tread, and lighting and the underrun guard must be complete for the roadworthiness test.
